Table 7-2 Effect of flow direction on outputs and totalizers

Fluid flow	Output or	Flowmeter configuration
direction	totalizer	Forward	Reverse
Fluid flowing	Milliamp output	Output increases as flow rate	Output goes to 3.8 mA
in same direction		increases
as flow arrow
	Pulse output	Output increases as flow rate	Output remains at 0 Hz
on sensor
		increases
	Internal totalizers	Flow totals increase	Flow totals remain constant
Fluid flowing	Milliamp output	Output goes to 3.8 mA	Output increases as flow rate
in opposite direction			increases
from flow arrow
	Pulse output	Output remains at 0 Hz	Output increases as flow rate
on sensor
			increases
	Internal totalizers	Flow totals remain constant	Flow totals increase

6.Internal damping filters out noise or the effects of rapid changes in the variable without affecting measurement accuracy.

The damping value is the filter coefficient that approximates the time required for the output to achieve 63% of its new value in response to a step change at the input. The actual time depends on many factors, including sensor type and density of the process fluid. The meter rounds down the chosen damping value to the nearest programmed filter coefficient. Programmed filter coefficients, in seconds, are:

0.1 0.2 0.4 0.8 1.6 3.2 6.4 12.8

If desired, enter an internal damping value into the Damping text box in the Flow panel.
